  • Publication number: 20150196813
    Abstract: A golf putter grip comprises a main tubular body having a non-circular cross-section being symmetrical and remaining similar throughout its axial length and a flat front area being also along and throughout its axial length. The non-circular cross-section and the flat front area respectively have a width sufficient to have two hands cupped together at the same height and two thumbs placed side by side on the flat front area to hold the putter grip comfortably with minimal wrist breaking-down. The non-circular cross-section can be in a shape of flat-topped arch, flat-topped washer, modified rectangular, modified square, modified triangular, hexagonal and other non-circulars. The main tubular body is reversely tapered, and its reverse taper is sufficient in certain degrees to accommodate different finger lengths of two hands for reducing the gripping pressure, so as to make the gripping comfortable.

  • Publication number: 20150196814
    Abstract: A single panel golf club grip includes a resilient inner sleeve and a single panel gripping member. The single panel gripping member has a laminate-layered structure having a panel decorative layer with a photographic image for aesthetical appearance and a contact layer for providing soft anti-slip feel. The photographic image is printed in one digital inkjet printing step in order to simplify and make the printing process cost-effective. An axial central part of the single panel gripping member is aligned with an axial central front area of the resilient inner sleeve for producing better visual effects, improving the good production rate, and proper grip alignment during installation.

  • Patent number: 8480508
    Abstract: A golf club grip comprises a resilient inner sleeve, a single sheet, an axial seam strip, and a combination of adhesives. The single sheet is wrapped around and adhered on to the resilient inner sleeve's body and has its top and bottom circumferential margins respectively over the resilient inner sleeve's cap underside edge and retaining sidewall edge, and two axial margins forming an axial gap along the length of the resilient inner sleeve's body. The combination of adhesives includes a pressure sensitive adhesive and a structural adhesive. The pressure sensitive adhesive is used to adhere the single sheet onto the resilient inner sleeve's body. The structural adhesive is applied in the axial gap covered with the axial seam strip to form an axial seam structure. The single sheet can be a leather/foam single sheet to provide the golf club grip with a soft and cushion feel for the user.

  • Patent number: 8308581
    Abstract: A golf club grip having an outer leather layer that includes a low water absorption leather and a polymeric protection coat. The low water absorption leather has a static water absorption range from about 30% by weight to 20% by weight after completely immersed in water for one hour and a range from 45% by weight to 35% by weight after completely immersed in water for six hours in the test method according to ASTM D6015. The protection coat is bonded to a grain surface of the low water absorption leather to retard the penetration of water and to protect the leather from damages. The outer leather layer is configured either as a single sheet or as a strip, wrapped and adhered onto a lining sleeve to cover a sleeve body of the lining sleeve to form a water repellent leather grip.

  • Publication number: 20060172815
    Abstract: A golf club grip includes a tubular body, a hard shell cap, and a single-sheet anti-slip skin. The tubular body includes an end portion having an end face extending transversely of the end portion, and a vent hole formed in the end face of the end portion. The end face is flat and has no projection around the vent hole. The hard shell cap is fastened removably to the end portion of the tubular body, and includes a cover plate axially covering the vent hole and projecting radially from the end face of the end portion of the tubular body, and a skirt portion extending peripherally and axially from the cover plate and abutting against an end portion of the single-sheet anti-slip skin. The single-sheet anti-slip skin covers correspondingly a wall surface of the tubular body.

  • Publication number: 20050209017
    Abstract: A golf club grip includes a sleeve body having a top cap and a bottom protective rim, and an anti-slip sheet layer extending around the sleeve body between the cap and the protective rim. The sheet layer has a top circumferential margin which is hidden and hemmed by the cap. The sheet layer further includes two axial margins which extend adjacent to each other and which are hemmed by an axial hem structure of the sleeve body. The axial hem structure extends from the cap to the protective rim to receive and hem the axial margins. As the margins of the sheet layer are hemmed and finished by the cap, the protective rim and the axial hem structure, no visible clearance is formed in the golf club grip.

  • Patent number: 6656057
    Abstract: A golf club grip includes a molded or shaped tubular foam body of closed-cell foam material and an anti-slip rubbery skin bonded integrally to an outer surface of the tubular foam body, thus a slip-on type of this invention is formed. The closed-call foam provides advantages, such as light weight with correct or standard size, a wide range of size and grip weights for personal choice. The tubular foam body has a capped end to cap a grip-mounting portion of a golf club shaft. In an embodiment of coiled strip type, the tubular foam body is cut spirally to form a coiled strip that can be wrapped spirally around the grip-mounting portion, and the capped end is formed as a cap which is integral with the coiled strip.

  • Publication number: 20030216192
    Abstract: A grip for a golf club includes a unitary inner layer tube with a butt cap and a tip ring, made of a resilient polymeric material, and adapted to be disposed around one end of the golf club. An outer layer is disposed around and is adhered to the inner layer tube, and includes a flexible sheet member having two opposite longitudinal ends along an axial direction of the inner layer tube. The sheet member is adhered to the inner layer tube by wrapping the sheet member, in a flat form, around the inner layer tube solely along a circumferential direction relative to an axis of the inner layer tube until one of the longitudinal ends reaches the other one of the longitudinal ends between the butt cap and the tip ring of the inner layer tube. The outer layer includes a plurality of anti-slip stitches thereon.
